Dairy was a big trigger for my IBS it was so bad I had to cut dairy from my diet completely. Everyone is different though and will have different triggers. My Dr did say though that dairy is a common trigger. I hope this helps.

Gonna depend, it's different for everyone! For me, sugary cereals are the biggest trigger for some reason. Doctors sometimes reccommend keeping a food diary so you can notice any patterns in what you ate + your symptoms

that actually makes so much sense for me now that I'm thinking about it thank you so much!

Strangly mine is tomatoes if they are overly processed I'm OK but fresh tomatoes or passata is a no no

Red sauces broccoli carrots or fatty meats have me running lol🥴 trying to be more mindful about what meal I ate when I had a flare up to kind of do the elimination diet but not too crazy fanatical about it to the point that I'm scared to eat haha I found that I was getting a little too much into my own head over it and was scared to eat to the point I was dropping lbs far too rapidly and needed to approach it in a much more healthy manner😬

if I have to eat dairy for some reason I always take a Lactaid pill. it helps a ton!

By far for me the worst is sugar, in all forms (sweets, fruit sugars like fructose in the FODMAP diet). I always get instant pain after eating anything sugary
